Arsenal boss Arsene Wenger hailed his side's complete performance in the 4-0 Champions League drubbing of FC Porto at the Emirates Stadium.
The Gunners put a weekend loss to Hull City behind them in style, with Robin van Persie and Emmanuel Adebayor both scoring twice against the Portuguese champions.
Wenger commented: "The most important thing was to respond quickly in a convincing way to the game against Hull and that's what we did.
"We were focused and I was happy with the attitude. Maybe we were too tense at the start of the game, but we were focused and at this level that is vital.
"It's difficult to measure our best performance of the season, but this was maybe our most complete performance.
"This is half the response I want. The other half comes on Saturday against Sunderland.
"I was tempted to make more than one change, but I didn't want to give the feeling that I was punishing one player more than another.
"I wanted to give the team the chance to respond quickly. The change was not to punish anyone, it was because we needed to respond quickly as a team."
